To all'zchom it may concern:

Be it known that I, Cmr'rox F. LEATHER BEE, a citizen of the UnitedStates, residing at Newton, in the county of Suitfolk and State ofMassachusetts, have invented certain new and useful Improvements inWood- Treating Machines, of which the following is a specification.

My invention relates to machines for ap plying liquids or fluids to thesurfaces of materials, and particularly to the provision of an improvedtype of apparatus which is adapted to paint, stain, varnish, fireproof,creosote, weatherproof and otherwise treat materials or generallysubject to the action of liquids, flooring, molding, cross arms andother lengths of wood or strips of moving material and for polishing andfinishing the same, coating them with insulation, etc.

The principal objects of my invention are the provision of a machine ofthe class described which is adapted to apply the liquid rapidly. easilyand economically, and to ap ply it with facility and thoroughly to allthe surfaces of material of irregular contour, especially such strips aspicture molding, wainscoting wall rails, conduit molding adapted tocarry electrical wires, and the like; to provide a machine which isadapted for applying a liquid to the edges of boards, and for thoroughlycleaning the material before it is treated and for rubbing the liquid inand removing the excess, after it is treat ed; to provide means wherebythe excess material may be removed from the machine to the supply tankand reused in order to avoid wastage, together with such other objectsas will hereinafter more fully'appear.

For the accomplishment of the objects above referred to, together withsuch other objects as will readily occur to those who are skilled intheart to which my invention pertains, I have provided theconstructionillustrated in the accompanying drawings, wherein i Figure 1 is asectional elevation. of a preferred form of my invention, taken on thethe line II of Figure 2.

Figure 2 is a plan view of the machine 01 Figure 1 taken on the lineII-II thereof.

Figure 3 is a sectional elevation taken on the line III-III of Figure 2to illustrate the means for supplying the liquid to the machine.

Figure 4 is a sectional view taken on the line IV-IV of Figure 2, toillustrate the contact of one of the finishing brushes when the liquidis to be applied to but a single surface of the. moving material,certain of the parts appearing in Figures 1 and 2 having been removed.

Figures 5 and (5 are respectively sections taken on the lines V-V andlines VIVI of Figure 2 to illustrate the adjustable mounting of theupper brushes and rolls.

Figures 7 and 8 are respectively a longitudinal sectional elevationtaken on the line VII of Figure 8, and a plan sectional elevation takenon the line VIII of Figure 7, to illustrate my preferred form ofconstruction simplified for the purpose of treating the moving materialon but a single plane or surface.

Referring to Figures 1 and 2 it will be seen that in carryingout myinvention, I provide a box like structure or casing 10 which Ipreferably locate adjacent the end of a planer .or other machine forforming molding, flooring and the like. In order to save theexpense anddelay incident to a rehandling of the material and to insure a straightfeed of the material to be treated through the machine, it should be fedby the live rolls of the forming machine. though it will be apparentthat if it' is desired to use my machine separately from the formingmachine, the material to be treated may be readily fed through a machineof my construction by the live rolls l1 and 12 located adjacent theretoor other convenient means.

For the purpose of cleaning the moving material in order that it may beproperly prepared for the reception of the liquid. and that theeffective application thereof may not be interfered with by the presenceof dust. chips. shavings or other detritus. I provide the oppositelydisposed pair of brushes 19 and 20. and in order that the waste removedfrom the moving material thereby may not clog the machine, the casing 10is left open at the bottom beneath such brushes as indicated at 21.

For the further polishing of the material preliminarily to theapplication of the liquid a second set of brushes is provided as indicated at 23, 21, and to thoroughly rub in and incorporate the liquidwith the surface of the moving material after removing any excessthereof, another oppositely disposed set of brushes and 2G is arrangedat the tail end of my machine.

- To assure the application of the treating liquid to the sides andedges of the moving material as well as to the broad or plane surfacesthereof, I provide preferably at right angles to the brushes heretoforedescribed a pair of oppositely disposed brushes 27 and 28.

Referring.particularly to' Figures 1 and 3 it will be noted that tofacilitate the application of the treating liquid, I have provided thetank 30 from which the liquid may be fed by the piping31, 3:2 and 33 tothe oppcsitely disposed spraying nozzles 35 and 36. The orifices of suchnozzles being regulable by the valve devices indicated at 37 and 38respectively and the volume of the liquid supplied thereto being furthercontrollable by the globe valves indicated at 39 and 40.

When the nature or purpose of the mov ing material to be treated is suchthat it is desirable to apply-the liquid to but a single surfacethereof, the valves. 39 and 40 may be closed and the liquid fed to thebrush 22 from the pipe 34 connectedto the pipe'31 and controlled by thevalve 42. From an inspection of Figure 1 it will be seen that the nozzleor end of the pipe 34, is so embedded in the brush 22 as to allow theliquid to feed the bristles of the brushes and thence, to be supplied tothe surface of the moving material, in such a manner as toprevent itfrom spattering and to confine it immediately to the surface which is incontact with such bristles.

To facilitate the removal of any excess of liquid given forth from thenozzles 35 and 36, or that may be removed from the moving material bythe brushes 25 and 26, I provide the casing 10 with a sloping bottomwhich drains into the trap 43 connected by the pipe 44 to a pump 45which may be of any convenient type adaptable for the purposes of myinvention. The pump 45 is connected by the pipe 46 to the tank 30 for atwo fold purpose; in the first place to return thereto the excess liquidfrom the trap 43 in order that it may not be wasted, and, second, tosupply pressure to the tank 30 inorder to force the liquid therefrominto the pipe 31, and thence to the nozzles 35 and 36. It will, however,be apparent that various other feed arrangements might be used,depending upon the character of the paint or stain used and of thematerial treated.

By reference to Figures 1, 5 and 6 it will be noted that the rolls 14,16 and 18 which serve to support the moving material, or both to supportand feed it. as well as the brushes 20, 24 and 26 which act upon thelower side of such material are removably fixed in position but are notnecessarily adjustable, whereas the corresponding rolls 13, 15 and 17are vertically adjustable in order that materials of different sizes anddiameters may be fed through the machine and maintained in desiredposition, such adjustability being obtained. by the respective en'-gagement of the bolts 47-47 with the slots 4848 in the yoke 49, in Whichthe ends of.

the shaft 50 carrying the roll are mounted,

(see Figure 6), and the brushes 1-9, 23. and 25 are likewise capable ofvertical adjust-v ment to facilitate the passage of the moving material,such adjustment being obtained by the respective engagement of the bolts57+ oi with the slots 585 8' in the yoke 59 in which the back 60 ofthebrushlf) is carried. hen the rolls and brushes have been adjusted tothe desired positions they gagement with the sleeves 69 and 70 inthesides of the casing 10 and through the slots 71 and 72 with theblocks 73 and 74 inthe brushes 27 and 28 respectively. These brushes mayalso be lifted and lowered vertically, for a purpose which willhereinafter appear, by means respectively of the screws 75 and 76 havingthreaded engagement with the sliding sleeves 77 and 78 car-. ried in theslots 79 and 80 in the top of the casing 10. e

It will be observed from Figures 3 and 5, as well as from Figures 1 and2', that the pairs of brushes, 19-20, 2324, 27428 and 25-26 are made ofirregular contour by the provision therein of series of tufts ofbristles of materially different lengths, (8182), which I have found itdesirable to provide for a number of reasons,'among others that by thisserrated form of brush the liquid may be applied to moving materials ofall contours however irregular, and

through the interlocking of the serrations in the edges of theoppositely disposed brushes the moving material is fully encompassed andno part thereof can escape the application of the liquid.

It will be further seen that a vertical adjustment of the brush 22 maybe had, where expedient, on account of the contour of the material to betreated, by loosening the ring 83 and moving the split friction sleeve84, (see Figures 1 and 7), and that the nozzles 35 and 36- may likewisebe adjusted vertically where the contour of the moving material or thegravity or visciclity of the liquid renders it desirable. I

From an inspection of Figures 1, Q and 4 it will be noted that when itis desired to apply liquid to but a single surface of a piece of movingmaterial, as for example anemia the underside of fa piece of flooring87,

(which is runupside down, as will appear ,from Figure 4, since thefinishing head of the flooring machine is on the under side thereof,resting directly on the body of the machine in order to obtain theminimum vibration), that is to say the upper side of the flooring as itcomes from the machine, I have provided the longitudinal tongued 'andgrooved members 88 and 89 adapted respectively to engage with acorresponding groove and tongue on the moving material 87, the saidmembers 88 and 89 being provided with felt strips '90--91 in order toprevent any excess liquid which may be applied to thefiooring 87 by thebrush 22 from passing beyond the sald tongues and grooves and therebystaining or discoloring the opposite surface of the flooring 87. As maybe seen most clearly in Figure 4, the

, members 88 and 89 are adjustable laterally by the screws92 and 93which have threaded engagement with the sleeves 94 and 95 inthe sides ofthe casing 10, the said screws 92 and 93 being respectively providedwith lock nuts 96 and 97 in order to hold the members 88 and 89 firmlyin place when they have been properly adjusted to receive flooring ofthe dimension then to be treated.

It will be, further observed from Figure 6 that the various series ofrolls such as 15 and 16 are preferably made in three sections 98, 99 and100 in order that when the supporting members 88 and 89 are used theymay respectively rest upon the at that time dead outer portions 98 and99 while the flooring 87 rides upon the live portion 100, though I havefound that equally satisfactory results may be attained in the case offlooring by the use of the simplified form of construction illustratedin Figures 7 and 8 wherein the members88 and 89 are supported at theopposlte ends on the casing 10. and upon the inner partition wallthereof 10 It is tobe understood that while I have illustrated themembers 88 and 89 as adapted to receive tongued .and grooved flooringthey may be readily adapted to receive material of other cross sectionwhich requires treatment on only part of its superficial area. Thearrangement of tongue and groove members provided with absorbent ordamming strips. will be found particularlyuseful in connection withmachines which a supply to the treating machine material ofextraordinary lengths, as for example veneering machines, and especiallyon such occasions as it may be found desirable to stop the machineswhile they contain mate:

rial in the process of formation and treat-' ment.

The mode of operation of the machine embodymg my inventlons and thebenefits and advantages thereof will be apparent from terial, incombination, a casing adapted to receive moving material, means forguiding the edge of the material, means for applying liquid to part ofthe material and means cooperating with the said guiding meanspreventing the application of the liquid to other parts of the movingmaterial. 2. In a machine for treating moving ma terial, in combination,a casing adapted to@ receive moving material, means for applying liquidto part of the moving material, a

-pa1r of strips for guiding the moving material, and felt strips on thesaid guides,

3. In a machine for ap lying a liquid to one face of tonguean grooveboards,

guide means fitting the edges of the boards and protecting them, and abrush adjacent the face of the board.

4. In a machine for treating material, the combination with. means forsupplying liquid to the material, ofa brush having an irregularlyserrated contour whereby the end portions of the longest bristles canflex,

independently of thefshorter.

5. In a machine-for treating materiaL'the I combination with means forsupplying liquid to the material, of a brush having tufts of bristles ofpointed or jagged contour whereby the bristles forming the end portionsof said tufts can flex independently of the shorter bristles.

In testimony whereof I have hereunto signed my namein the presence ofthe two subscribed witnesses.
